T 0 ctZZ whom it may concern.-

Be it known that I, LUIS DUQUE, a resident of the city of Paris, France,have invented certain new and useful Improvements in Telephone-ReceiverSupports; and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, in which- Figure 1 is a perspective View of a telephone withmy invention shown applied, a portion of the casing being shown brokenaway. Fig. 2 is a detailed enlarged View, in side elevation, of thedevice with the telephone-receiver only shown and arranged in theposition it has when in'use; and Fig. 3 is a top plan view thereof withthe receiver shown in dotted lines and the position of parts in dottedlines when the receiver is not in use.

Letters of like name and kind refer to like parts in each of thefigures.V

The object of my invention is to provide a compact, efficient, andsimple support for telephone-receivers adapted to yieldingly h old thereceiver with a gentle pressure against the ear and to automaticallyproduce the closing and opening of the talking-circuit; and to theseends said invention consists in the telephone-receiver support andcircuit-controller having the features of construction substantially ashereinafter specified.

In the carrying of my invention into practice I employ a horizontalbracket-arm that is composed of two members A and B, that are hinged orpivoted together on a vertical axis by a pin (J and the former providedwith a laterally-extending foot or lug a, by which it may be fastened,as by screws, to the Wall or other surface adjacent to the telephone. Abrace-bar D, attached to the member A on the under Side and adapted tobe secured to the wall, is provided to firmly hold the arm in place.Connected at its opposite ends to the two arm members, so that itextends across their hinge or pivot, is a coil-spring E, that normallytends to flex the arm by pulling the member B, so that it stands at anangle of about Seventy degrees from the position it occupies when italines with the other member. The outer end of the member B is forked,and in the fork is pivoted on a horizontal pivot and clamping-screw F anarm G, at whose outer end is attached the support or holder H for thetelephone receiver I. The arm G is telescopic or capable of beingextended or shortened to enable the position of the receiver-holder tobe adjusted horizontally, and consists of two rods, one of which istubular or hollow to receive the other and has a set-screw g for fixingthe relative positions of the rod. Vertical adjustment of thereceiver-holder is had by swinging the arm G on its pivot-screw F, theclamp being relaxed to permit Such swinging and tightened when thedesired position is attained.

The telephone-receiver Shown is of the common form, and the holder H isgiven a shape and construction suitable for it. It comprises a concavemain portion with a C shaped spring-clamp 72, to partially embrace thebod; part of the receiver as it rests in said main portion and an openor slotted end portion h to accommodate the annular enlargement on theend of the receiver. Said enlargement by engagement with the oppositesides of said end portion 7?. acts as a Stop to prevent endwise movementof the receiver in the holder.

Pivoted at one end by a screw K to the side of the arm member A is avertically-movable bar L, that is bowed or curved horizon tally and atits other end is pivotally connected to one arm of a bell-crank lever M,that is pivoted to the side of the arm member B. The other arm of saidlever is connected to the lower end of a vertical rod N, having a hookat its upper end that engages the telephone-receiver hook andcircuit-controller O of common form. When the spring E is free to actand pulls the arm member B out of alinement with the member A, the barL, acting on the bell-crank lever M, causes the latter, through the rodN, to pull down the hook O, and thus produce the same effect as does thereceiver when hanging from the hook. When the ear is applied to thereceiver on the arm G and the member B is moved against the pull of thespring to place it in alinement with the member A, the separation offected causes said lever to be rocked to lift the rod N and permits theupward movement of the receiver-hook O to close the circuit.

On the side of the arm memberA opposite that to which the spring isattached is fastened a small plate P, an end of which is in suchposition that it will engage and stop the movement of the arm member Band the parts connected therewith.

It will be seen that the talking-circuit is automatically closed whenthe receiver is moved in the direction to stretch the spring E and thatit is automatically broken by its movement in the opposite directionunder pull of said spring when the head of the user is removed from thereceiver. If the user, having occasion to leave the telephone, yetdesires that the circuit be kept closed, such may be done simply bydisengaging the rod N from the hook 0.

It is to be understood that though the construction shown is preferred,nevertheless other embodiments of the invention may be made whosestructure specifically will vary from that shown.

Having thus described my invention, what I claim is 1. The combinationof an arm made of two members hinged together, one of whichisconstructed to support a telephone-receiver and the other to be fastenedin a fixed position, a spring attached to the arm to move the formermember, and a' part on said arm constructed for connection with thecircuit openmg and closing mechanism of a telephone, and movablerelative to the arm, that is moved to close the circuit when the movablearm member is moved against the action of the spring, and is moved toopen the circuit when said arm member is moved by the action of thespring, substantially as and for the purpose described.

2. The combination of an arm made of two members, one of which isconstructed to sup port a telephone-receiver, and the other to befastened in a fixed position, a spring attached to the arm to move theformer member, a le-. ver pivoted to the movable member, means forconnecting it to the circuit opening and closing mechanism of atelephone, and connections between said lever and the fixed arm member,whereby the movement of the movable lever in opposite directions causesopposite movements of the circuit opening and closing mechanism,substantially as and for the purpose described.

3. The combination of an arm made of two members hinged together, one ofwhich is constructed to support a telephone-receiver, and the other tobe fastened in a fixed position, a coiled spring fixed at its ends tosaid members, for moving the former, a lever pivoted to the movablemember, a bar connected at one end to the latter, and at the other endto the fixed member, and a rod attached to said lever, to connect thesame to the telephonecircuit opening and closing mechanism,substantially as and for the purpose described.

at. The combination of an arm made of two members, hinged together, oneof which is constructed to be fastened in a fixed position, and theother is movable and provided with a pivoted, telescopic,receiver-supporting arm, a coiled spring connected at each end with saidmembers, a lever pivoted to the movable member, a bar pivoted to saidmember at one end, and at the other end to said other arm member, and arod attached to said lever, adapted for connection with thetelephonecircuit closing and opening mechanism, substantially as and'for the purpose described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
